Modeling of beam-column joints

Post by Zonghu Pei » Tue Feb 25, 2025 1:45 am

Hello, STKO Team:

I am building a beam-column-slab joint model. In order to better simulate the experiment and simplify the connection of BTED and PC column into rigidlink, two node link is used for the bolted connection between BTED and the end plate. I have tried many ways to connect the nodes. However, the model does not converge. I don't know what the problem is. Can you help me modify the model (The model is in the attached zip package) ?

Thanks very much.

Ps:Here is the Disassembly diagram of the model

Hi, There is one issue with your model - review at how you model the connection between the beam and slab. Attached figure shows the issue. Also, I don't think you can aggregate section response in dispBeamColumn elements, only forceBeamColumn works with the aggregators. There may be other issues as well. Thnak you.
